| Myo-elastic Aerodynamic Theory |
|
Definition
oscillation of the vocal fold maintained exclusively by muscular and aerodynamic processes
Muscular process occurs in the body of the vocal folds
Aerodynamic Process=Bernoulli Effect |

Definition
The maintenance of intra-thorasic pressure through the active opposition of inhalation/exhalation muscle systems
*which means*
All the organs in the rib cage work together with muscles involved with respiration to produce breath |

Term
| Vertical Phase Difference |
|
Definition
-measures DURATION
-measures how long the vocal folds stay together during one cycle of compression/rarefraction (period)
Starts when bottom of VF come together
Stops when top of VF come apart |
